Definitions

  • the invention relates to a valve with a valve housing and a shut-off element, the valve housing having a cavity for receiving the shut-off element, an inlet opening for a fluid to flow into the cavity and an outlet opening for the fluid to flow out of the cavity, the shut-off element having a guide body and is arranged linearly movable at least partially in the cavity of the valve housing between the inlet opening and the outlet opening.
  • molded cellulosic articles are made by forming cellulose solutions in an organic solvent and spinning the cellulose / solution melt to form a fiber or film.
  • a preferred form of the solvent is a tertiary amine N-oxide, typically N-methyl-morpholine-N-oxide (NMMO).
  • NMMO N-methyl-morpholine-N-oxide
  • the DE 38 15 897 C2 shows a start-up valve throttle unit with a discharge channel that widens to form an extrusion tool.
  • a guide and start-up bore is provided in which a start-up valve and throttle body is arranged displaceably and rotatably in the direction of its longitudinal axis, transversely to the axis of the discharge channel.
  • the start-up and throttle body has two closing sections, between which a throttle body is arranged.
  • a start-up valve body is formed on an inner closing section on the side facing away from the throttle body.
  • valves are, for example, from the DE 27 512 25 , the DE 10 2007 047 726 and the DE 10 2005 037 268 famous.
  • the object of the present invention is to alleviate or remedy at least individual disadvantages of the prior art. It is a particular object of the invention to provide a valve in which fluid flows are improved.
  • a valve with a valve housing and a shut-off element
  • the valve housing having a cavity for receiving the shut-off element, an inlet opening for a fluid to flow into the cavity and an outlet opening for the fluid to flow out of the cavity
  • the shut-off element having a guide body and is arranged linearly movably at least partially in the cavity of the valve housing between the inlet opening and the outlet opening, the shut-off element having at least one recess for the fluid to flow from the inlet opening via the recess to the outlet opening.
  • the shut-off element has at least one recess for the fluidic connection of the inlet opening to the outlet opening.
  • fluidic connection means that a fluid can flow from the inlet opening to the outlet opening.
  • the recess of the shut-off element is thus a throughflow recess which enables fluid to flow between the inlet opening and the outlet opening, so that the outlet opening is open.
  • the shut-off element is at least partially in the Cavity of the valve housing arranged between the inlet opening and the outlet opening, so that the shut-off element is at least partially positioned in the flow direction of a fluid flowing in the cavity between the inlet opening and the outlet opening.
  • the recess By moving the shut-off element linearly, the recess is displaced linearly, so that the fluidic connection between the inlet and outlet opening is separated and a fluid flowing from the inlet opening into the cavity of the valve housing is prevented by the shut-off element from flowing further to the outlet opening. As a result, the outlet opening is blocked and closed by the shut-off element.
  • the linear movement of the shut-off element including the recess is infinitely variable so that the outlet opening to be shut off can be shut off variably between 0 and 100%. This enables stepless regulation of the fluid flowing through the outlet opening.
  • the recess of the shut-off element is a recess which reduces the cross section of the shut-off element compared to a section of the shut-off element adjacent to the recess. When arranged in the cavity, this adjacent section seals the cavity in such a way that a fluid flowing into the cavity via the inlet opening is prevented from flowing to the outlet opening, so that the outlet opening is blocked by the shut-off element. If the shut-off element is moved so that the recess is arranged in the cavity instead of the adjacent section, the shut-off element does not seal the cavity due to the smaller cross section in the area of the recess, so that at least one fluidically connecting the inlet opening with the outlet opening through the recess in the cavity Opening is formed.
  • Fluid can flow from the inlet opening to the outlet opening via this at least one opening. Due to the stepless movement of the shut-off element, the recess can be partially arranged in the cavity so that the at least one opening formed by the recess is only formed by the part of the recess arranged in the cavity, so that the size of the opening by changing the portion arranged in the cavity the recess can be varied.
  • the recess can, for example, 5% to 95%, preferably 10% to 90%, or 20% to 80%, or 30% to 70%, on the longitudinal axis of the blocking element (linear direction of movement) make up the normal cross-sectional area compared to the cross-sectional area of the adjacent blocking section.

  • the valve according to the invention can be used for the supply, discharge, switching and / or delivery limitation of highly viscous liquids and / or melts without dead space. Due to the special design of the shut-off element, the valve can be used for highly viscous liquids and melts in the area of partially crystalline high-performance thermoplastics, such as PEK (polyether ketone), PPEK (polyphthalazine ether ketone), PPS (polyphenylene sulfide), or amorphous high-performance thermoplastics such as PAI (polyamideimide), PPSU () PSU (polysulfone) or PES (polyethersulfone) can be used in the corresponding manufacturing processes.

  • Such methods and manufacturing processes typically include extrusion, injection, blow molding, coating and spraying techniques, such as e.g. B. the production of synthetic textile fibers, plastic hoses, plastic foils and films as well as protective and / or insulating coatings for electrical conductor wires.
  • the valve according to the invention is preferably used in the production of cellulose or in lines for the transport of cellulose solutions.
  • the valve according to the invention is particularly preferably used in the transport of cellulose solutions which are used as Extrusion media are used for the molding process.
  • the cellulose concentration is selected in the usual sizes for lyocell processes.
  • the cellulose concentration in the cellulose solution can be 4% to 23%, preferably 6% to 20%, in particular 8% to 18% or 10% to 16% (all% figures in% by mass).
  • the solvent of the cellulose solution is preferably a tertiary amine oxide (amine-N-oxide), particularly preferably N-methylmorpholine-N-oxide.

  • the shut-off element can easily be moved linearly in the longitudinal direction of the guide body in the cavity.
  • the shut-off element is easy to manufacture possible.
  • the recess is a recess in the prism-shaped guide body, so that the constant cross-section of the prism-shaped guide body perpendicular to the longitudinal axis is smaller in the region of the recess. As a result, a smaller cross section is blocked off by the shut-off element in the region of the recess, so that fluid can pass through the shut-off element and flow to the outlet opening.
  • the recess is a taper in the guide body, the taper being preferably arranged perpendicular to the longitudinal axis of the (prism-shaped) guide body.
  • the recess thus forms a groove running around the guide body perpendicular to the longitudinal axis, along which a fluid can flow around the shut-off element transversely to the longitudinal axis of the prism-shaped guide body. This allows fluid to flow via the inlet opening into the cavity of the valve housing and further along the taper to the outlet opening.

  • the recess is an opening in the guide body of the shut-off element.
  • the opening is advantageously a cylindrical bore through the guide body, which is preferably aligned perpendicular to the longitudinal axis of the prism-shaped guide body.
  • the opening can fluidically connect the inlet opening and the outlet opening of the valve housing, so that a fluid can flow from the inlet opening through the opening to the outlet opening.
  • the shut-off element has a further recess.
  • the fluid can flow from the inlet opening to the outlet opening by moving the shut-off element linearly over the recess and / or the further recess.
  • the shut-off element is positioned in the valve housing by linear movement in such a way that the recess and / or the further recess fluidically connects the inlet opening with the outlet opening, so that a fluid can flow from the inlet opening to the outlet opening.
  • a sample of a material can be taken both during ongoing production and during discharge (for example with the aid of a start-up valve). Furthermore, the pressure can be relieved with the further recess.
  • the further recess is an opening, preferably a prism-shaped opening, particularly preferably a cylindrical further opening, in the guide body of the shut-off element.
  • the recess is a cylindrical opening
  • the diameter of the recess can be smaller, equal to or larger than the diameter of the cylindrical further opening of the further recess. If the diameter is the same, the further opening can be used as redundancy for the opening. With different shapes of the recess and the further recess or different diameters of the cylindrical opening and the cylindrical further opening, different flow velocities can be achieved in the opening and in the further opening.
  • the further recess is a prism-shaped opening in the guide body of the shut-off element, preferably a longitudinal axis of the prism-shaped guide body and a longitudinal axis of the prism-shaped opening at an angle between 45 ° and 90 °, particularly preferably between 60 ° and 85 °, in particular between 70 ° and 80 °.

  • the further recess is preferably designed for conveying the fluid from the inlet opening to the further outlet opening. The inlet opening is thus fluidically connected to the further outlet opening via the further recess.
  • the cavity has an essentially prism-shaped first section and an essentially prism-shaped second section, the shut-off element being at least partially accommodated in the second section so as to be linearly movable.
  • the first section is preferably fluidically connected to the second section so that fluid can flow from the first section into the second section and vice versa without the shut-off element arranged in the second section.
  • the base of the prism-shaped second section has the same shape as the base of the prism-shaped guide body of the shut-off element.
  • the base area of the guide body can be smaller than or equal to the base area of the second section, so that the shut-off element can be accommodated in the second section with a tolerance greater than or equal to 0. This enables the shut-off element to be optimally received in the cavity of the valve housing.
  • the first and second essentially prism-shaped sections intersect at an angle between 30 ° and 90 °, preferably between 60 ° and 90 °, particularly preferably between 80 ° and 90 °, in particular of exactly 90 °.

  • an outlet opening is arranged on a second base area of the essentially prism-shaped first section opposite the first base area, in particular is congruent with a second base area of the substantially prism-shaped first section opposite the first base area.
  • the inlet opening and the outlet opening are preferably arranged on a longitudinal axis of the first section, so that an optimal fluid flow can arise in the cavity of the valve housing.
  • the axis along which the shut-off element can be moved is particularly preferably aligned perpendicular to the longitudinal axis of the first section, so that the shut-off element can be moved perpendicular to the fluid flow in the first section of the cavity.
  • the first section is essentially cylindrical, the diameter of the essentially cylindrical first section in an area of intersection of the first section with the second section being 1% to 20%, preferably 5% to 10%, smaller than in the case of the first base area.
  • the second section is a cylindrical bore penetrating the valve housing, the bore forming a first and a second opening on two opposite sides of the valve housing.
  • a simple and inexpensive manufacture of the valve housing is thereby possible in that the second section of the cavity is manufactured through a bore.
  • the shut-off element can thus easily be arranged in the second section of the cavity of the valve housing and removed again from the second section of the cavity for maintenance purposes.
  • the guide body of the shut-off element is essentially cylindrical, the longitudinal axis of the cylindrical second section coinciding with the longitudinal axis of the essentially cylindrical guide body of the shut-off element.

  • a defined fluid flow can flow around the guide body of the shut-off element through the gap, so that no dead space is formed in the cavity in which fluid can be deposited. Long dwell times of the fluid in the valve according to the invention are prevented by the absence of dead space.
  • the recess of the shut-off element is advantageously designed in such a way that it does not form any dead space when a fluid flows against it and enables the fluid to be passed on in an optimal manner. This is the case, for example, in the case of a narrowing as a recess.
  • the tolerance is in particular (also) given in the adjacent section blocking the constriction.
  • a seal is arranged between the guide body of the shut-off element and the cavity, which seal seals the shut-off element with respect to the valve housing.
  • the essentially cylindrical guide body of the shut-off element is at least partially received in the bore in such a way that the shut-off element protrudes at least partially from the second opening.
  • sealing rings preferably leakage rings, are mounted in a groove milled into the guide body of the shut-off element.
  • These sealing rings are preferably constructed from a flexible plastic ring that is resistant to the fluid and from a cover ring.

  • the sealing rings can particularly preferably be bulged inwardly into the second section of the cavity in the direction of the guide body by tightening fastening screws that fasten the sealing rings to the valve housing, so that the fluid flow in the gap in the second section of the cavity between the guide body and the valve housing is reduced.
  • the valve has a drive for linearly moving the shut-off element, the drive engaging at an end of the shut-off element protruding from the second opening.
  • the shut-off element can be partially arranged in the cavity of the valve housing in a space-saving manner.
  • the invention further relates to a valve system with a valve as described herein, a start-up valve being provided in a further cavity that leads to the inlet opening of the valve.
